(2) This oxygen-bridged corner-sharing polyhedral network breaks up long-range crystalline order, facilitating low-temperature amorphization. The highly disordered local environment lowers the activation energy barrier for moving lithium ions, increasing room-temperature ionic conductivity (\u0026gt;1 mS\/cm).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSintering Kinetics \u0026amp; Volatilization In Garnets\u003c\/strong\u003e: When using Li2O for oxide-based ceramics like Cubic LLZO (Li7La3Zr2O12): (1) At typical solid-state calcination temperatures (\u0026gt;1000 C), Li2O exhibits a very high vapor pressure. If it volatilizes unhindered, the system undergoes a phase transition into the poorly conducting pyrochlore phase (La2Zr2O7). (2) A 10 to 15 mol% excess of the Li2O precursor must be budgeted into the starting batch. The green compact is typically shrouded in a sacrificial \"mother powder\" of identical target composition to create a localized, saturated Li2O vapor atmosphere inside the crucible, blocking bulk net lithium loss from the core sample.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 367.288px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 46.8875px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 46.8875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 46.8875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCBSSEPCLO (C-BSSE-PC-LO)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e12057-24-8\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026gt;99.9%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003e\u003cem\u003eMolecular Weight\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e29.88 g\/mol\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003eWater Level\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e\u0026lt;0.005 wt% (battery grade)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003eD50\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e8.65 um\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003eMelt Point\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e1427°C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003eDensity\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e2.013 g\/mL at 25 °C(lit.)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 30.5755%; height: 35.6px;\"\u003ePackage Grade\u003c\/td\u003e\n\u003ctd style=\"width: 69.0647%; height: 35.6px;\"\u003e\n\u003cp\u003e\u003cspan\u003e50 g\/bottle\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e: Please store the Li2O powder in a dry place (glovebox is preferred).\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e: \u003c\/span\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0167273817301546\"\u003e\u003cspan\u003eA.
